IMPROVEMENT IN SAD-IRONS.

Specification forming part of' Letters Patent No. 206.369, dated July 23, IETS; application filed May 14, 1878.

To all whom it may concern:

Be it known that I, HENRY Il. TODD, of West Meriden, county of New Haven, State of Connecticut, have invented new and useful Improvements in Sad-Irons; and I do hereby declare that the following is a full, clear, and vexact description of the same, reference being had to the aceompanyin g drawings, and to the letters of reference marked thereon.

This invention relates to that class of sadirons in which a shell or box, forming the iron proper, is employed in connection with a removable heating-block and consists in certain peculiar details of construction by means of which cert-ain imperfections in the ordinary irons are remedied, and certain special advantages are obtained, as will be l'ully described hereinafter.

In the drawings, Figure l represents a side elevation of my improved iron; Fig. 2, a vertical sectional elevation of the same, the space about the heater being shown in solid black; Fig. 3, a transverse section on the line m a', Fig. 1 Fig. 4, a plan view ot the shield detached 5 Fig. 5, a transverse section of the box or shell; Fig. 6, a plan view of the heating-block removed, and Fig. 7 a side elevation ot the same.

To enable others skilled in the art to make and use my invention, I will now proceed to describe fully the manner of eonstructin g and using the same.

A, Figs. l and 5, represents the box or shell, constructed generally in the usual form, but essentiallyprovided with the opening a, Fig. 5, at its rear end, and the projections al a2 a2 upon the `inner face of its bottom plate, as shown.

B B, Figs. l and 2, represent standards or arms rising from the upper plate of the iron in the usual manner, which support the usual handle C in any proper manner.

D, Figs. 2 and 4, represents ashield of any proper material and suitable size, which is suspended below the handle C, as shown, for the purpose of protecting the hand ot' the ironer from the heat of the iron.

E, Figs. l, 2, and 3, represents the door for `:losing the rear opening of the shell, consist` ing of the flap or drop portion e, Figs. l and 2, adapted in size and shape to close the opening a, Fig. 5, when in its proper position, and

the lever portion cl pivoted near its front end between the standards or ears e2 by means of the pin eil, as shown. The rearend of the lever portion, it will be observed, is bifurcated to pass the rear standard I3, and is united at its eXtreme edgeto the upper edge of the flap portion e, the two parts lying at right angles to each other, as shown. The front ends ot the lever portion are also bifurcated to form a vertical recess for the lower end of the actuating-rod.

F, Figs. l and 2, represents the rod, united at its lower end to the front end of the lever portion e* of the door, and properly supported above by the guide ear or plate f, projecting from the handle G, as shown. f1 represents any proper knob or handle attached to the upper end of the rod, and Pf3 catch-notches, by means of which and the guide-earf the handle may be secured in either its upper or lower position for the purpose of holding the door open or shut.

G, Figs. 1 and 2, represents a spring o't any proper construction, by means ot' which, when adjusted in either may be securely held against accidental displacement.

H, Figs. 2, 6, and 7, represents the heatingblock, corresponding in its general outlinewith the shell or box A, designed to receive the same, which is essentiallyprovided with the recesses h1 h2 h2, corresponding inform and po` sition with the projections al a2 a2, as shown.

h3, Figs. 2 and G, represents a vertical open ing through the block, and h4 a transverse bar located in the vertical center ot' lsaid opening, near one end, as shown.

h5, Figs. 2, 6, and 7, represents a pin located at the point of the block, and It h6, Figs. 6 and 7, pins located on the sides of the block, near its rear end, the purpose of which is to center the block in the shell while new, and before it becomes swelled by the heat, after which they may be removed by breaking them ott.

AEach face or" the heater is constructed alike, so that it may be used either side up.

I, Fig. 7 a, represents a lifter of any proper' construction for removing the hot block II from the lire and inserting it in the shell, and for removing it from the shell and inserting it in the fire.

position, the actuating-rod The operation is substantially as follows: The block H, having been properly heated in the re, is removed by the lifter and inserted into the shell, the door having been opened for the purpose. IV hen the block is properly in place, the recesses of the same will coincide with the projections upon the bottom plate of the shell, and hence the tormer will be securely held in its place, and not be permitted to slide about and knock against the ends and sides. After the block is in place the door may be closed by simply swinging the actuating-rod in a rearward direction upon its pivot against the action ot' the spring` G sufciently far to disengage its upper notch from the -guideear, when the door, bein g no longer su1')ported, will fall by its own weight properly into place.

The door is so hung, it will be observed, as to tightly close the openin g when it swings to place, and thus eit'eetually prevent the escape of heat. rEhe door may be raised at any time when it is desired to remove the heater by simply depressing the knob of the actuatingrod until the upper notch of the same is caught by the guiding-ear.

Some of the advantages ot` the described construction are as follows: The heatingblocl; when in place is securely held in its proper position, so that the noise caused in other irons by the knockin et the block against the sides and ends is avoided.

By means of the peculiar construction ot' the door a joint is obtained which will not be atl'ectcd by the expansion resulting from the heat, but will remain equallyv tight under all circumstances. 1

The opera-tion ot the door also in opening and closing is convenient and easy.

I do not contine myself to the t'orm ot' pro- `iections and recesses shown. It desired, they may be round, instead of oblon It' desired, also, the projecting points h5 7b may be employed to hold the heater from. sliding in the shell. l

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with the drop-door, moving in avertical plane and having a lever-arm pivotcd at one end to the iron, an actuatingrod, substantially as described, for moving the lever-arm.

2. In combination with the drop-door and connecting` lever, the aetuatin g rod, having notches f2, the spring Gr, and plate f, substantially as described.

3. In a sad-iron, a drop-door at the rear thereotl attached to an arm pivoted near the front ot' thc sad-iron, and operated by a parallel projecting thumb-lever, substantially as shown and described.

This slieeiication signed and witnessed this 2d day ot' May, 1878.
